Science Class 1-28-11

Today, we looked over the homework and talked about how the reactants of photosynthesis are products of respiration. (C6H12O6 + 602 --->)
(6CO2 + 6H20)



It made sense the formula was opposite because they do opposite things.



We reviewed that photosynthesis takes place in the chloroplasts and the cellular respirtaion takes place in the mitochondian. Plants need oxygen for cellular respiration or energy. We also talked about how we need light to live because without light, plants wouldn't be alive, which is bad since some of our food comes from plants. We discussed we needed energy to exercise and also take in CO2 and glucose. We exhale more CO2 after we exercise because we're doing cellular respiration, which takes up more energy.

  1. Cellular Respiration's equation is C6H12O6 + 602 --->6CO2 +6H2O which is the opposite of Photosynthesis' equation which is: 6CO2 +6H2O--->C6H12O6 + 602. The reactants are the stuff before the yields arrow and the products are after the arrow.

  2. This is Saad:)
    The correct respiration equation is
    C6H12O6+602 --->6CO2+6H2O+ATP(chemical energy)

    The reactants are glucose and oxygen, and the products are CO2, water and ATP

    Also for photosynthesis it should be Light+6CO2+6H2O-->C6H12O6+602

    The reactants are light CO2 and water, and the products are glucose and oxygen
